The process of converting a biopolymer from its denatured state to native state occurs spontaneously with the evolution of 40 kcal of heat to the surroundings per mole of polymer denatured at the 37 degrees Celsius. At constant pressure this process can be regarded as a phase change. Entropy is equal to -0.129 kcal/mol-K, Enthalpy of combustion equals -40kcal/mol, Gibbs free energy (G) equals 0 kcal/mol. Determine the delta Cp for the process D to N assuming delta Cp is independent of temperature.
